The massive underground bunker for the two 16-inch guns of Battery Murphy is at center. It is oriented almost exactly north-south. The two gun positions are shown on the eastern side of the bunker, and its three drive-in truck entrances are on the western side. To orient the map, the coordinates of the center of the eastern edge of the concrete canopy covering Btty Murphy Gun 1 are given above. The plotting room for this battery is shown at the center of a large mound of protective cover at the extreme western edge of the map, with two entrance portals opening towards Swallow Cave Rd. on its western side.
The twin 6-inch gun positions of Battery 206 are shown at lower left. Each gun position occupies a flat portion of seaside ledge, and they are joined by an underground central magazine bunker, which has portals to each side and a portal to the northwest, which was used to deliver ammunition to the bunker.
The two temporary Panama mounts for the 155mm guns are shown in the lower right-hand corner of the map. Today, only the remains of Gun 1 are visible at the surface, the mount for Gun 2 having been graded away during previous redevelopment of the Point.
Also visible, just south of 155mm Gun 1 and right at the water's edge, is the cable hut which served as the terminus for the Navy's underwater magnetic loop cable segments which were used to monitor the northern approaches to Boston Harbor and survives to the present. The structure to the southwest of this (marked "Navy building [by others] on the map) was used to house the Navy personnel who monitored the magnetic loop detection system.
Today, Northeastern University, which uses the former Btty Murphy bunker as a marine research facility, has administrative offices and classrooms (in a recycled 1950s Nike missile site building along the road on the west side of Btty Murphy, roughly in the area of the "MESS HALL" indicated on the 1945 map.
